Product Introduction

Portal Slewing Crane is a port crane used for loading and unloading operations with a grab or hook at the front of port terminals and open-air stockpiles. It has a strong lifting capacity of tens to thousands of tons and can easily lift various heavy objects. Portal Slewing Crane is divided into two types: single-arm and four-link according to the boom structure. Its 360° rotating platform and tilting jib system provide a wide range of working ranges, coordinated and adjustable speed of the working mechanism, and efficient operation. The advanced control system can adapt to various harsh environments and different operating scenarios. With a sturdy and durable structure and flexible travel mechanism, it is an ideal solution for operations in ports, shipyards, etc.

The electric drive adopts the unique technology of full digital Ac frequency conversion and PLC speed regulation control with flexible control and high precision.

At present, the specifications of the main products are MQ1025, MQ1030, MQ1625, MQ1630, MQ1635, MQ2525, MQ2530, MQ2535, MQ4025, MQ4030, MQ4035 single boom portal slewing crane and four-link portal slewing crane.

Application

Portal slewing crane is versatile and applicable to many places, including factories, warehouses, and construction sites. It is suitable for moving materials and equipment, as well as loading and unloading trucks and containers. The portal slewing crane is easily movable, promoting optimal utilization of available space. It offers a flexible and ergonomic solution for diverse lifting needs when a stationary crane is not required.

It is also popular in ports, docks, storage yards, and other places to complete the loading, unloading, and transshipping operations of ships and vehicles. lts design, manufacturing, and inspection implement the latest domestic.

Portal Slewing Crane Advantages

Wide working range

The rotary platform of portal slewing crane can rotate 360°, the boom can be tilted, and the working area is large and can be covered in all directions. In the harbor, shipyard and other complex environments, it can lift goods from different positions, reducing the time of equipment movement.

High operating efficiency

Lifting, luffing, slewing, walking (partially) and other mechanisms work together, and the operating speed can be adjusted, so it can load and unload goods quickly and accurately, and improve the speed of logistics turnover in ports and the efficiency of shipyard construction.

Highly adaptable

Adapt to a variety of harsh environments, such as harbor salt spray, shipyard complex space. Parameters and configurations can be adjusted as needed to meet the needs of different scenarios.

Accurate lifting

With advanced control system, it can precisely control the lifting operation with small error, which can protect valuable or precise goods and guarantee the safety and quality of operation.
